Default transient problem

Actually We are working in transient analysis of first stage Gas turbine Nozzle with Prostar.

I have a question in the way we want set the boundary conditions, this because we are working the input region with a table option (R=radial position of the blade lengt[mm], TEMP, DEN, V)I mean, the table contains 4 parameter R=independet variable, (TEMP,DEN,VElocity=dependent variable).

In the case of transient, I need another aditional table with a new dependent variable..the time, I want to set the boundary condition TEMP; DEN; VEL) depending of TIME AND RADIAL POSITION....HOW can I do THAT??

Actually I have results with boundaries depending of Radial position....But we need both independent variables (time and Radial pos.)

Another problem is a error message that appears : ERROR #211 *** INSUFFICIENT DIMENSIONS FOR THE CONDUCTIVITY ARRAY.INCREASE PARAMETER NCTMXC OR NBTMXC AND RECOMPILE. ?????I had increased this parameters in the parm.inc, but the problem still appears.....

Iīd appreciate any information yuo can give me...

best regards

Hi Why donīt you try with bcdefi.f user subroutine? Reagrding the parameters, you have to increase them from within prostar. Best regards Roadracer
